The below Parliamentary question was asked by Lord Berkeley on 2016-06-28.
To ask Her Majesty’s Government whether the Thames Tideway Tunnel project will send clean excavated materials to landfill permit sites as a waste or to be beneficially reused as a material or product as recovery in accordance with its commitment to reduce waste to landfill in the development consent order.
Lord Gardiner of Kimble
Tideway, the infrastructure provider set up to finance and deliver the Thames Tideway Tunnel, has been assessing several sites identified through the Development Consent Order (DCO) process to receive the tunnel excavated material.
Amongst other things this assessment looks at maximising the beneficial use of excavated material and its transport by river to meet environmental commitments made under the DCO. The relevant site operators have already made a number of applications to the Environment Agency (EA). The type of permit these sites require will be assessed by the EA in line with its guidance. This guidance is currently being revised following a recent Court of Appeal judgment which in some cases may lead to the reclassification of some waste activities as disposal rather than recovery. It is possible for appropriate disposal to deliver beneficial use such as habitat creation.
